C44.1

Clinical Causes: Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds Fair or light skin complexion, which provides less natural protection against UV exposure Chronic skin injuries or wounds in the eyelid region History of skin cancers or other predisposing skin conditions Exposure to certain chemicals or radiation Genetic predisposition or family history of skin cancers

Key Symptoms: A new or changing growth or sore on the eyelid that doesn’t heal A growth feeling like a lump or thickening on the eyelid Persistent redness or inflammation of the eyelid Ulcerated or bleeding lesion Change in color or size of a pigmented spot on the eyelid Discoloration or scaling that persists or worsens over time

Diagnosis Path: Diagnosis typically involves a thorough examination of the eyelid and surrounding skin by a healthcare professional. This may include visual inspection, dermatoscopy, and biopsy procedures such as excisional or incisional biopsy to confirm the presence of malignant cells. Imaging studies like ultrasound, CT scans, or MRI may be employed if the cancer has spread locally or to nearby structures. Accurate staging is essential for planning treatment strategies and involves assessing tumor size, depth, and potential spread.

Treatment Protocols: Treatment options vary depending on the size, location, and extent of the tumor. Common approaches include: - Surgical excision: Removing the tumor with clear margins, often combined with reconstructive procedures to restore eyelid function - Mohs micrographic surgery: A precise surgical technique that minimizes tissue removal while ensuring complete cancer removal - Radiotherapy: May be used in cases where surgery is contraindicated or as an adjunct post-surgery - Topical chemotherapy or immunotherapy: In select cases, topical treatments such as 5-fluorouracil or immune modulating agents can be used - Follow-up care: Regular monitoring to detect any recurrence or new lesions early Multidisciplinary management involving dermatologists, ophthalmologists, and oncologists is often essential for optimal outcomes.
